The nature of the oral cavity and host behaviors has mandated that the oral microbiota
evolve mechanisms for coping with environmental fluctuations, especially changes in the …

Bacterial signal transduction systems are responsible for sensing environmental cues and
adjusting the cellular behaviour and/or metabolism in response to these cues. They also …

Background The catabolite control protein A (CcpA) is a member of the LacI/GalR family of
transcriptional regulators controlling carbon-metabolism pathways in low-GC Gram-positive …

Laboratory adaptive evolution studies can provide key information to address a wide range
of issues in evolutionary biology. Such studies have been limited thus far by the inability of …

Background Antibiotic exposure rapidly selects for more resistant bacterial strains, and both
a drug's chemical structure and a bacterium's cellular network affect the types of mutations …

Bacteria such as Escherichia coli will often consume one sugar at a time when fed multiple
sugars, in a process known as carbon catabolite repression. The classic example involves …

In Escherichia coli, the phosphoenolpyruvate–carbohydrate phosphotransferase system
(PTS) is responsible for the transport and phosphorylation of sugars, such as glucose. PTS …

This review aims to familiarize the reader with research efforts on the cultivation media of
lactic acid bacteria (LAB). We have also included a brief discussion on standard ingredients …

Bacteria release low‐molecular‐weight by‐products called secondary metabolites, which
contribute to bacterial ecology and biology. Whereas volatile compounds constitute a large …

The phosphoenolpyruvate: sugar phosphotransferase system (PTS) is a carbohydrate
transport and phosphorylation system present in bacteria of all different phyla and in …
